Guest for glory 2 map. the resolution is to low, it is impossible to read

A few of the street names could be a bit clearer, but it looks to me like that was a problem with the original map, not a problem introduced by digitizing it. The sha1 sums for the files I looked at are:

Are there any street names you can read? If so, where on the map are the streets you cannot read?

A Google search for "Quest for Glory 2 map" leads me to http://www.qfgs.net/qfg2/info/maps.html, which features a GIF of the same map, where someone has redone all the labels in a more legible script. You might prefer this over the one included by GOG.

Here is a good map: http://www.legendsofglory.com/img/MapShapeirlarge.png

No streets names though.
